TECHNICAL FIELD

The present invention relates to a window frame structure for use in apartments, detached dwellings, apartment units in a private house, residential/commercial combined buildings, or the like, and more particularly, to a structure of a window frame capable of easily enlarging a veranda space as a living room or a room according to the convenience of residents.

BACKGROUND ART

Recently, residents or appointed tenants enlarge a space of a living room or a room so far as a veranda to more effectively utilize the space, if necessary.

FIG. 1 is a schematic cross-sectional view illustrating the structure of a conventional window frame for a living-room.

Conventional living-room window or ventilation window 1 includes, as shown in FIG. 1, an interior window 2 and an exterior window 3, the interior and exterior windows slidingly moved along a window frame 4. The window frame 4 consists of one support frame secured to a ceiling, a floor and both walls.

The interior window 2 and the exterior window 3 slide from side to side along a pair of guide rails 4 a disposed on the ceiling and floor and spaced apart from each other at certain intervals. At that time, the guide rails are outwardly exposed, with they faced to each other.

In the case of a balcony window (not shown) having a parapet, there is at an outermost position a repellent window 6 for blocking off enter of flies, mosquitoes or the like.

However, since the respective guide rails disposed at the ceiling-side supporting portion of the window frame and the floor-side supporting portion of the window frame which support the interior and exterior windows and the repellent window are vertically protruded from the ceiling and the floor, there is a drawback in that the window frames are left as it is or are removed when constructing the veranda to utilize the veranda space.

In particular, since the guide rail disposed at the floor-side supporting portion of the window frame is concavely formed, dusts are collected on the concaved portion of the guide rail, thereby frequently cleaning the guide rail.

Also, since the floor-side window frame is higher than the indoor floor, it is possible to fall over the window frame.

Furthermore, rollers provided to both ends of the interior and exterior windows are directly abutted against the upper and lower guide rails of the window frame when sliding along the guide rails. Accordingly, even if there is a slight eccentricity between the interior and exterior windows and the guide rail when sliding along the curved window frames, it is difficult to open or close the window.

DISCLOSURE OF THE INVENTION
